  • Biomarkers
  • Information


Testosterone is a steroid hormone found in males and females however, its role is amplified in males. It is responsible for the regulation of libido, bone and muscle mass, mood changes and fertility determination. The testosterone levels are prevalent in men during puberty when it peaks and often decreases over age. An increase in testosterone levels is associated with  testicular issues in males.

Sex Hormone Binding Globulin (SHBG)

Sex Hormone Binding Globulin is a protein present in the bloodstream. SHBG is produced by the liver. The role of SHBG is to bind testosterone and oestradiol for circulating in the tissues of the body. The concentration of SHBG is directly relative to the level of hormones in males or females. SHBG is checked to detect low levels of testosterone in males and high levels in females.

Free Thyroxine (FT4)

FT4 or free thyroxine is one of the two critical hormones produced by the thyroid gland. While it is produced in greater abundance as compared to FT3, it is thought of as a reservoir for FT3 whenever the body needs and this leads to conversion of FT4 into FT3. Most of the thyroxine is not attached to a protein and the Menopause blood test helps to identify if there's a deficiency/excess of the hormone to detect thyroid related ailments.

Thyroid Stimulating Hormone (TSH)

TSH (Thyroid Stimulating Hormone) or thyrotropin is secreted by the pituitary gland, located in the head, and can help identify cases of hypothyroidism and hyperthyroidism. Both the excess and under-secretion of TSH can lead to weight loss, anxiety, palpitations, irregular sleep patterns and irregular menstrual cycles. Hypothyroidism is majorly associated with overlapping symptoms such as menopause.


To check inflammation levels, we conducted an advanced CRP evaluation. C-Reactive Protein (CRP) is a protein found in the blood which increases in response to inflammation. CRP is produced by the liver in response to inflammation. It is a biomarker of inflammation that is strongly associated with the risk of cardiovascular disease, such as heart attack and stroke. High levels of CRP are found in people with chronic inflammatory diseases, such as rheumatoid arthritis, and in people who have had a recent heart attack or stroke. CRP is not a specific marker for any one disease, but it is a valuable indicator of inflammation.

Free Androgen Index (FAI)

Predominantly, testosterone has a significant function in men. Testosterone is bound to albumin and SHBG. Free Androgen Index (FAI) helps you detect any changes in the androgen levels of your body. FAI is calculated for those who suffer from PCOS or Hirsutism for checking any rise in non-protein bound testosterone.

Ferritin (Iron Levels)

Ferritin is the protein that stores iron in the body. Iron is needed to provide muscles with oxygen so that they receive the energy they need to function properly. Ferritin will release the iron when needed and is kept within the body's cells, most commonly found in the liver. We check ferritin levels to ensure that there is proper storage of iron in the body's cells otherwise the iron will be depleted quickly.




Total Iron-Binding Capacity (TIBC)

Transferrin Saturation

Unsaturated iron-binding capacity (UIBC)

Free Triiodothyronine (FT3)

Free triiodothyronine (FT3) is a crucial hormone that plays a pivotal role in regulating various metabolic processes within the human body. FT3 is a form of thyroid hormone that is unbound and freely available for immediate use by cells. Produced by the thyroid gland, it influences a wide range of physiological functions, including metabolism, growth, development, and thermoregulation. FT3 exerts its effects by binding to specific receptors located in various tissues, initiating gene transcription and ultimately affecting cellular metabolism. It is responsible for regulating the basal metabolic rate, energy production, and utilisation of carbohydrates, proteins, and fats. Furthermore, FT3 is essential for maintaining normal cardiovascular function, neurological development, and reproductive health. Precise measurement of FT3 levels is crucial in diagnosing and monitoring thyroid disorders, such as hyperthyroidism and hypothyroidism, allowing for accurate assessment and appropriate treatment to restore hormonal balance and overall well-being.


Albumin is a protein present in blood plasma and plays a binding role like SHBG. Albumin is produced by the liver. Albumin will help to detect any issues in the functioning of the kidney or liver. It prevents the fluid in blood vessels from leaking out.

Why take the test?

Hair Loss is often caused due to a vitamin deficiency or hormonal imbalance. A lack of iron in the body can cause hair thinning or lead to excessive hair loss. Similarly, abnormal thyroid function is known to affect hair regrowth thus, your hair may not restore itself as it would otherwise. A treatment of the deficiencies or thyroid imbalance can treat hair loss and help in growth of hair.

Brilliant product!

It was fascinating to gain an insight into the common factors defining hair health. I learnt a lot about where I may be lacking certain nutrients and this will drive my supplement and lifestyle decisions moving forward. Really pleased, would definitely recommend.

Theodora Restrepo

It's important to choose a pharmacy that is able to offer medication delivery options to a variety of locations, including workplaces and schools.

Jade Farrar

I was skeptical at first but the hair-loss-blood-test was surprisingly easy to use and super informative. It helped me understand my hair loss issues better. Results were quick and accurate. Highly recommended for anyone dealing with hair loss!

Jamal Hassan
Not recommended

Had to pay for my test kit, three times as sample can be messed up by the company itself and sometimes the carrier (delivery company) either way you will have to pay to do another test.😅
